' HYDROCARBON-MOTOR.

Patented Feb. 20, 1906.

Application filed December 19, 1904- Serial No. 237,868.

To all whom it may concern.-

Be it known that I, ABBo'r AUGUSTUS Low, a citizen of the United States,residing at Horseshoe, St. Lawrence county, State of New York, haveinvented certain new and useful Improvements in Hydrocarbon-Motors, of.

hydrocarbon mixed with air simultaneously with alcoholic vapor, alsoadmixed with air, into a common mixing-chamber preparatory to theadmission of the combined charge into the combustion-chamber, the jarranement being such that either the hydrocar on or the alcohol can be usedseparately and independent of the other when desired.

- The invention consists in the construction and arrangement of artsherein described and claimed specificall ,whereby the feed of either oiland air or alcohol and air, orboth,

may be regulated simultaneously in due and prescribed prolportionsubstantially as here- .mafter set fort In \the accompanying drawings,Figure 1 represents diagrammatlcally and in sectional elevation partsessential in carrying out my invention. Fig. 2 is a detail view upon anenlarged scale. Fi 3 is a transverse section taken upon lane 0 line 33,, Fig. 2.

The su p y of hydrocarbon to the injector h is regu ated throu h themedium of 'the valve h, the stem'h" 0 which is threaded and engages witha rotatable nut-gear j, mounted in the cross-bar 7c of the yoke K. Thenut-gear j engages with apimon 1 upon the shaft L,'mounted on the yoke Kand-rotatable by means of a crank or wheel I. Another nut-gear i, alsomounted on the crossbar k of the yoke K, likewise meshes with thedrivingimon l and engages the threaded stern n o a valve n",communicating with the mixing-chamber on one side, and with a pipe. at,commumcatmg with a compressedair reservoir 11. or other means of.supplying air under pressure. The screw-threads on the valve-stems h andn are reversed with relation to each other, so that on the rotation ofthe shaft L and driving-pinion Z they will be raised or loweredsimultaneously with relation to their respective valve-seats; but thismotion-will not be uniform for the et er than the nut-gear 3'. Thus insimultaneously'opening the valves n h the area of the air-valve will beincreased relatively in proportion to the area of the hydrocarbon-valvein accordance with the re uirements and in a definite and prescribeproportion. Instead of a difference in diameter between the nut-gears yy" the difference in motion of the valve-stems may be effected by adifferent pitch 'ofthe threads upon the valve-stems k 'n.- In eithercasethe result is the same, the supply of air bein regulated andproportionate to the supply 0 hydrocarbon, relatively more air beingadmitted with every increase in the oil-feed. In like man:

ner the supply of alcohol to the injector-1'. is regulated throu h themedium of the valve '11, the stem i of wIiich is threaded and engageswith a rotatable nut-gear 0, mounted on a cross-bar b of the yoke B. Thenut-gear 0 engages with a pinion 9 upon the shaft Q, mounted upon theyoke B and rotatable by means of a crank or wheel q Another nutgear 1',also mounted on the cross-bar b of the yoke B, likewise meshes with thedrivingl-pin- 1011 g of the shaft Q and engages wit the threaded st emtof a valve 25 communicatin with the mixing-chamberA on one side, an

with a pipe u, communicating with a compressed-air reservoir U or othermeans of supplying air under pressure. The screw.-

threads on the valve-stems t and tv are reneously o ening the air andalcohol valves the area of t e air-valve will be increased relatively inproportion to the area of the alcoholvalve in accordance withrequirements and in a definite. and prescribed roportion; As in the caseof the hydrocarl f on-supply instead versed with relation to each other,sothat on roe of a diflference in diameter between the nutears a likeresult may be attained by a diference in screw-pitch.

Relief-valves 'v v are preferably interposed inthe oil and alcohol pi'es and arranged to conduct the overflow om the injectors back throughpipes 0 0 to the forcing mech anismH L.

By the differential and simultaneous adj'ustment of the supply of airunder pressure Thus the hydrocarbon is so thoroughly impregnated withoxygen that combustlon is instantaneous and complete, and there is noresidual deposit of unconsumed carbon.

. What I claim as my invention, and desire to secure b Letters Patent,is-

- 1. In a ydrocarbon-motor, the combination. of a combustion-chamber, amixingchamber, an inlet-valve interposed between said combustion-chamberand mixing-chamber, an intersticed screen in said mixingchamber, meansfor injecting a jet of hydrocarbon fuel against said screen, means forinjecting'a jet of compressed air against said screen, and meansforeflecting a simultaneous but differential adjustment of the quantityof fuel and compressed air injected against said screen in themixing-chamber, for the purpose described.

2. In a hydrocarbon-motor, the combination of a combustion-chamber, amixingchamber, an inlet-valve interposed between said combustion-chamberand mixing-chamber, an intersticed screen insaid mixing chamber, meansfor injecting a jet of hydro- I n 0 C I carbon fuel against sald screen,means for m-- o ing or diminishing the quantity of fuel and compressedair injected against said screen 1n the nuxmg-chamber, for the purposedescribed.

3. In a hydrocarbon-motor, the 'combina- 7 tion of a combustion-chamber,a mixingchamber, an inlet-valve interposed between saidcombustion-chamber and mixing-chamber, an intersticed screen in saidmixingchamb'er, means for injecting a jet of hydrocarbon fuel-againstsaid screen, means for injecting a jet of compressed air against saidscreen, the injectors being arranged convergently with relation to eachother so that the ets of hydrocarbon and compressed air im-' I 55' pingeagainst each other at or near the center of said screen, and means foreflecting a simultaneous but difierential adjustment of the quanity offuel and compressed air injected against said screen in themixing-chamber,

for the purposedescribed.

4. In a hydrocarbon-motor, the combination with a mixing-chambercommunicating with the combustion-chamber, of means for I simultaneouslysupplyin alcohol, and hydrocarbon to said mixing-c amber, and means forvarying and adjustin the supply of compressed air thereto in aifferentlal but pre.

scribed proportion, for the pur ose set forth.
